Hello, I have 2 kind of questions. [1] Is there a reference for set Data Region & Cache configuration?? I don't know exactly how to configure data&Cache... so, I looking for reference or best practice of cache&data region set up. Is it normal case divide data region by domain/business purpose area??
[2] I have 3 nodes at remote server and I use java thin client in application. I found these error in log file. how can i fix it? or is it not problem?
